Furthermore, as shown in fig. 2, after the front lock body 311 and the rear lock body 312 are assembled, the insertion block 3124a may be inserted into the insertion groove 3115a, so that the rail groove 314 formed by the first rib 3115 and the second rib 3124 includes a first rail groove 3141 located on the upper side of the insertion block 3124a and a second rail groove 3142 located on the lower side of the insertion block 3124a, and the first rail groove 3141 and the second rail groove 3142 are independent of each other. At this time, the first track groove 3141 is in the shape of a U-groove with an upward opening, and a stopper 32 located on the upper side is slidably mounted therein; the second rail groove 3142 is formed in a U-groove shape with a downward opening, and another stopper 32 located next time is slidably mounted therein.

However, if only one end of the stopper member 32 is slidably fitted into the track groove 314, the free end of the stopper member 32 is likely to be bent. Therefore, in the embodiment of the present application, as shown in fig. 4, the rail grooves 314 are disposed at both ends of the position limiting member 32, so that both ends of the position limiting member 32 can be slidably mounted on the lock body 31. Specifically, the first ribs 3115 are two in number and located on the left and right sides of the lock hole 3112. The two second ribs 3124 are located the left and right sides of lockhole 3112 respectively, and each second rib 3124 can match the first rib 3115 that is located lockhole 3112 homonymy and form track groove 314, finally makes the even atress in stop part 32 both ends and difficult the inflection, has improved stop part 32's life.

In order to prevent the stopper member 32 from moving in the axial direction thereof, a stopper structure may be provided on the stopper member 32 to limit the degree of freedom in the axial direction of the stopper member 32. In the embodiment of the present application, as shown in fig. 4, since there are two first ribs 3115 and two second ribs 3124, the limiting structure may be two limiting shoulders 321 arranged on the side wall of the limiting part 32, and the two limiting shoulders 321 are arranged in the axial direction of the limiting part 32. During assembly, the two limiting shoulders 321 may be sandwiched between the two first ribs 3115 and/or the two second ribs 3124, or the two first ribs 3115 and/or the two second ribs 3124 may be sandwiched between the two limiting shoulders 321.

In other embodiments, the limiting structure may also be two limiting medium installed on the limiting part 32, and any one of the first rib 3115 and/or the second rib 3124 may be sandwiched between the two limiting medium.

In order to make the two ends of the position limiting component 32 uniformly stressed, there are two elastic elements 34, the two elastic elements 34 are respectively used for connecting the ends of the two position limiting components 32 on the same side, and the two first ribs 3115 are located between the two elastic elements 34.

Referring to fig. 6 and 7, fig. 6 is a first structural schematic diagram of a locking hook of a clothes dryer door lock provided in an embodiment of the present application, and fig. 7 is a second structural schematic diagram of the locking hook of the clothes dryer door lock provided in the embodiment of the present application. Two end portions of the locking hook 33 in the axial line direction thereof are a locking end 331 and a fixed end 332, respectively.

As shown in fig. 6, as a first structure of the locking end 331: a boss 3311 is provided on one of two side walls of the locking end 331 facing the position restricting part 32. The protrusion 3311 may include a first arc surface 3311a and a second arc surface 3311 b.

The first arc surface 3311a is located on a side of the protrusion 3311 near the end of the locking end 331, and is in an arc surface shape protruding outward away from the axis of the locking hook 33. Therefore, in the process of inserting the lock hook 33 into the lock body 31, the position-limiting component 32 abutting against the first arc surface 3311a and the first arc surface 3311a form a wedge transmission structure, and the first arc surface 3311a penetrating through the two position-limiting components 32 drives the two position-limiting components 32 to move back and forth; in the process, the elastic member 34 is stretched.

The second arc surface 3311b is located on a side of the protrusion 3311 away from the end of the locking end 331, and is in the shape of an arc surface that is concave toward the axis of the locking hook 33. Therefore, during the process of inserting the lock hook 33 into the lock body 31, when the second arc-shaped surface 3311b passes through the two position-limiting members 32, the two position-limiting members 32 gradually gather together with the decrease of the protruding height of the protrusion 3311 under the restoring force of the elastic element 34, i.e., the two position-limiting members 3311 start to move toward each other under the action of the elastic element 34; until the second arc surface 3311b completely passes over the two stopper parts 32, the two stopper parts 32 clamp the latch hook 33 under the restoring force of the elastic member 34.

On the contrary, when the locking hook 33 is pulled out from the lock body 31, the two position-limiting members 32 are driven by the second arc surface 3311b to move back and forth, and then driven by the elastic element 34 to move back and forth. In the embodiment of the present invention, in order to increase the force required for pulling the locking end 331 out of the body 31, the adjacent ends of the first arc surface 3311a and the second arc surface 3311b are directly connected. Specifically, the method comprises the following steps: under the condition that the sizes of the first arc surface 3311a and the second arc surface 3311b are not changed, compared with the case that the adjacent end portions of the first arc surface 3311a and the second arc surface 3311b adopt the fillet transition, the connection portion of the second arc surface 3311b and the first arc surface 3311a adopts the non-fillet transition so that the end edge of the second arc surface 3311b close to the first arc surface 3311a is steeper than the slope of the axial lead of the lock hook 33, and therefore, a larger acting force is required to enable the limiting component 32 to pass over the second arc surface 3311 b. Therefore, the embodiment of the application has the advantage of good locking effect.

As shown in fig. 7, as a second structure of the locking end 331: the locking end 331 is provided with protrusions 3311 on both side walls facing the position restricting part 32. The protrusion 3311 may include a first arc surface 3311a and a second arc surface 3311 b.

Of course, in other embodiments, the locking end 331 may also be tapered, so that the two position-limiting members 32 can pass through and expand between the two position-limiting members 32 during the process of inserting the locking end 331 into the lock body 31.

The fixing end 332 has a mounting structure to facilitate mounting to the door body. In the embodiment of the present application, the mounting structure may be a disk-shaped seat 3321 disposed at the end of the fixed end 332, and the axial lines of the seat 3321 and the locking hook 33 are perpendicular to each other. When the lock hook 33 is installed, the seat body 3321 can be placed on the installation plane of the door body 20, and then the seat body 3321 is fixed by the corresponding positioning component on the door body 20. Of course, the seat body 3321 may also be provided with a screw hole, and after the seat body 3321 is placed on the installation plane of the door body 20, an external screw passes through the screw hole to lock the seat body 3321 to the door body 20.
